CHAIR.

Specification of Letters Patent.

Patented June 17, rain.

Application filed December 8, 1916. Serial No. 135,904.

To all whom it may concern:

Be it known that I, EUGENE BEnNmoHA'Us, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Chairs, of which the following is a specification.

My invention relates to improvements in barber, dental and similar chairs. One of its objects is to provide on a vertically adjustable chair an apron or shield carried by the chair to protect the operative mechanism from dust, lint, hair, and similar materials. Another object is to provide an apron to operate telescopically with the base of the chair and to conceal and protect the operative mechanism, and which may be finished in enamel or otherwise to correspond with sanitary qualities and appearance of the finish applied to other parts of the chair.

My invention also comprises certain details of form, combination and arrangement, all of which will be fully set forth in the de scription of the accompanying drawings in which:

Figure 1 is a perspective view of a barber chair embodying my improvements:

Fig. 2 is a sectional detail of the base, illustrating one form of lifting mechanism and my improved apron applied thereto.

Fig. 3 illustratesa modification of Fig. 2.

The accompanying drawings represent the preferred embodiments of my invention in which A represents the base on which the chair is supported. B represents the standard which is attached to the under side of the chair seat D and supports the chair body adj ustably as to height with reference to the base.

Any type of standard B may be employed to adjust the height of the chair. I preferably employ a hydraulic type of lifting mechanism in which the standard B constitutes the hydraulic plunger which telescopes into a cylinder formed in the base, and in which E represents the handle of a pump and valve mechanism to pump a liquid from the interior of the standard B into the cylinder of the base below the standard B to force the standard B upwardly, or at another position of the handle E. to open valves to permit the fluid to escape from the cylinder into the lower end of the plunger.

Whether the standard be mechanically elevated or hydraulically elevated, its parts are machined and to a greater or less extent coated with oil which causes dust, lint and hair to tend to collect on and adhere to said standard.

Also these chairs are now generally re quired for sanitary reasons and appearance to be finished in white or light enamels, and it is impracticable to enamel the finished operative faces of the adjusting mechanism. I therefore, in order to protect the finished operative faces from accumulating dirt and dust provide an annular or tubular apron H which may be attached directly to the under side of the chair bottom by means of projecting lugs h, as illustrated in Fig. 2, or which may be secured to the upper end or head I) of the standard B as illustrated in Fig.- 3. The apron H hangs downwardly concentrically about the standard B so as to protect the standard from dirt and dust, and so that the apron or shield shall telescope freely over the upper portion of the base as the chair is raised and lowered. In order to give strength to the apron H and prevent it being damaged or dented, or its enamel cracked, I preferably provide it with an inwardly turned flange at its lower free end and taper the body thereof as illustrated. The exterior of the base and trimmings of the chair are usually finished in light colored enamel, and the apron H may be likewise finished eXteriorly and thus have the appearance of being an upward extension of the base, and without in any way interfering with the operation of the standard B or vertical adjustment of the chair. It will be noted that as illustrated in Figs. 2 and 3 the standard B is firmly supported by and at the upper extremity of the base, thereby avoiding lateral movement of the chair relative to the base, or lost motion between the standard and base, and that the apron in no way interferes with this firm support of v the chair.

The mechanism herein illustrated and described is capable of considerablemodifica tion without departing from the principle of my invention.

Having described my invention, what I claim is.

1. A chair comprising, a base having a vertically disposed cylindrical upper section and a horizontally extended lower section, a chair seat, a standard having an enlarged head section attached to the chair seat and a cylindrical section seated and vertically' adjustable in a cylindrical recess in said base, a

standard adjusting member projectin laterally from the enlarged head section 0 said standard close to said seat, and an annular apron carried rigidly relative to and exteriorly of said standard and movable telesoopically over the exterior of the upper section of said base.

2. A chair comprising, a base, a chair seat,

a member intermediate of said base and chair seat to adjustably support said chair seat relative to the base, an adjusting member carried by and at the upper end of said adjustable supporting member and projecting laterally therefrom, and an annular apron member havlng an mturned flange at its lower edge carried rigidly relative to and exteriorly of said intermediate member and EUGENE BERNINGHAUS.
